BTW, does it not hurt your conscience, blinding the oncoming "less privileged" traffic with your HID glare? Can't really blame others when you meet with an accident ... can you?

go to any Car oriented marketplace, ask for the "headlight" guy.
He will remove the units, seperate the glass/plastic and the reflector/housing, wash and clean it thoroughly, and reseal.

DO NOT PAY MORE THAN 600 BUCKS FOR THIS!!

If its just dust and fade, it will be fixed.
do get both done, incase the old one gets a RIN safedi.
in not a lot of time, your lamps will eventually get similar age level look

It looks at it should. Many modern headlamps have a plastic front 'glass'. Excellent, but it does abrade faster. Also, the reflector will be sowing its age. I will prefer not to do anything, in a couple of months both will look about the same. If you must then try and polish the old one with toothpaste (the old white type which contains talc or powdered Gypsum) or Jewellers Rouge. Nothing harsher should be used.

If there are others who are also facing this issue, you might want to check this out:

Or, you could try the rubbing at it with toothpaste, which should help a little bit.

Hope this helps.

Guys,
Last night while coming home from office, i noticed that my 100/90s didn't light up my path as they used to. I inspected the headlamps after coming home and was shocked to see this.
What could be the reason for it? HASS as usual blames the usage of non OEM bulbs. However, I'm not convinced yet. Been using these since march 2011. Why has this blacked out suddenly?
robbers at HASS are charging 4 grand to replace the entire dome ! Yeek! Help me out guys.

Well I could not see anything.
Seems you have not attached the pic that was intended.

Please attach the pictures so that everybody can see what has happened.

@wild child>> what car are you using? and if you could post a picture of the headlamps wit would be much easier to give you a suggestion on how you could solve your problem.
there are cases where the fault is with the bulbs and sometimes the reflector. so, a picture would be really helpful.

Guys,

Some things you must know about Headlights:

1. Polishing the front perspex 'glass' does just that. It does nothing for the inside of the sealed unit.
2. If soap & water is used to clean the inside of the sealed unit via the bulb insertion holes, that water MUST be of a 'demineralised' quality (battery water). If you use hard water, after drying, there will be ugly marks inside which you CANNOT get rid of!
3. If only dust is on the inside of the unit, blowing with compressed air is enough.
4. ALL headlights (OEM, aftermarket etc) emit UV radiation, plus, there is enough UV from the sun as the car is left in the open. UV damages the silver coating inside the sealed unit. This is irrepairable. So, eventually ALL headlights fade.
5. OEM bulbs are coated with a UV reduction coating (as per manufacturers specs) plus, are less powerful than the 90/100 watt units. Therefore the headlight silver coating lasts longer with OEM bulbs.

I used Formula 1 Scratch Out on my old Santro (7+ years) and it did a lot of good. Did not do the wet and dry paper bit but it was still acceptable. Toothpaste may be too mild an abrasive.

use steel wool, the flattened variety.
You can basically apply as little or as much pressure as you want, with some kitchen cleaner.I used Mr.Muscle.
It'll work wonders, especially on water marks.

Mayankk, can i see a pic of the 'flattened' variety of steel wool? The normal ones at big bazaar & other shops will DEFINATELY scratch the relatively delicate perspex on the headlight.

[mayankk]

This one.
Got to be gentle though, as you would with anything else.
I cleaned my lamps with this, and then realized it was the projectors that were themselves bad.
(another story,that was)
